A recent discovery by Malwarebytes has identified a cyber threat involving a typosquatted domain that mimics official Microsoft support pages. This site uses authentic branding and KB-style reference numbers to deceive users into downloading what appears to be a legitimate cumulative update. The malware, once installed, operates stealthily, stealing passwords from browsers and active sessions, which allows attackers to bypass two-factor authentication. The stolen data is sent to external servers through encrypted channels. Initial scans showed zero detections by multiple antivirus engines due to the malware's obfuscated scripts. It also modifies system startup entries and creates disguised shortcuts for persistence. Microsoft has not yet released Windows 11 version 24H2 to general users, and updates should only be obtained through official channels to avoid potential threats.
